Just for the record a barber dime will (should) read 38 on the Safari. The best advice I can give you in regards to the Safari is to buy Andy Sabisch's Quattro & Safari Handbook, it will pretty much tell you everything you will need to know about the Safari. Because of how fast the Safari goes through batteries, it is highly recommended that you use some type of rechargable batteries. I keep 16 on hand and fully charged at all times, that way if I were to forget to recharge them from the day before, there are still 8 fully charged ones to fall back on if needed. It is helpful to have 2 chargers that hold 4 AA batteries each, that way you can charge 8 at a time. Many of us find that the 11" Pro coil is the only one we need for the Safari as it has excellent separation abilities for being a large coil. If you are going to be hunting a lot of iron or trash infested sites, then a smaller coil such as the 6x8" SEF coil might work best. If you don't like looking at the target icons being shown on your screen, they can easily be eliminated by "cross-saving" the coin or the coin and jewelry mode to either the relic or all-metal mode. Because of the Safari's large DD coil, it is best when pinpointing a target to swing over it from two different directions so as to get your most accurate pinpoint. For better depth, manually set your sensitivity rather than use the auto mode. Most of us run our trash density set on the high setting which is your factory preset position. One last thing, the Safari should be swung a little slower than most other detectors to get best results.
